The PRECISE-LOG series of data loggers are eight-channel, WIFI-enabled data loggers. They record various parameters such as voltage, current and temperature.

PRECISE-LOG promises to utilize state-of-the-art technologies yet affordable and cost-effective solutions to deliver the most accurate measurement, reliable long term performance and easy remote communications.

Its 8MB memory size, 16-bit ADC, 10-year battery life (when work in standalone mode), rugged aluminum housing and many other unique features make it second to none with the best price/performance ratio.

All of MEI data loggers are designed and manufactured in Canada to ensure the highest quality standard.

A data logger is an electronic or battery-powered instrument that records environmental conditions such as temperature,
relative humidity, and light levels over periods of time. Data loggers are connected to a computer terminal and proprietary software is used to download the recorded data and produce needed reports.
One of the primary benefits of using data loggers is the ability to automatically collect data on a 24-hour basis.
Upon activation, data loggers are typically deployed and left unattended to measure and record information for the duration of the monitoring period.
This allows for a comprehensive and accurate picture of the environmental conditions being monitored, such as air temperature, and relative humidity.

Data logging versus data acquisition

Data loggers typically have slower sample rates. A maximum sample rate of 1 Hz is a speed that may be considered to be very fast for a data logger, yet very slow for a typical data acquisition system.
Data loggers are implicitly stand-alone devices, whereas a typical data acquisition system must remain tethered to a computer to acquire data.
This stand-alone aspect of data loggers implies on-board memory that is used to store acquired data. Sometimes this memory is very large so it can accommodate many days,
or even months, of unattended recording. This memory may be either a battery-backed static random access memory, flash memory, or EEPROM.
Given the extended recording times of data loggers, they typically feature a time- and date-stamping mechanism to ensure that each recorded
data value is associated with the date and time of acquisition. As such, data loggers typically employ built-in real-time clocks whose published drift can be an important consideration when choosing between data loggers.
Data loggers range from simple single-channel input devices to complex multi-channel instruments.
Typically, the simpler the device is, the less programming flexibility it has. Some more sophisticated instruments allow for
cross-channel computations and alarms based on predetermined conditions.
The newest of data loggers can even serve web pages, allowing numerous people to monitor a system remotely.
The unattended and remote nature of many data logger applications implies the need in some applications to operate from a DC power source, such as a battery. Solar power may be used to supplement these power sources. These constraints have generally led to ensure that the devices they market are extremely power efficient relative to computers. In many cases they are required to operate in harsh environmental conditions where computers will not function reliably.
This unattended nature also dictates that data loggers must be extremely reliable. Reliability is a necessity since they may operate for long periods nonstop
with little or no human supervision, and may be installed in harsh or remote locations. It is also imperative that as long as they have power, they do not fail to log data for any reason.
Manufacturers go to great lengths to ensure that the devices can be depended on in these applications. As such dataloggers are almost completely immune to the problems that might affect a general-purpose computer in the same application, such as program crashes and the instability of some operating systems.
